Purpose

This webpage/report is intended to aggregate information from different agencies (i.e. USACE, SFWMD, FWC, USGS and NOAA) into one spot to help inform local government agencies and stakeholders on conditions within Lake Okeechobee, the Northern Estuaries and the Everglades ecosystem. The data provided here should be considered preliminary and are subject to change.

CRE Discharge Salinity Envelope - 6 months plot

Caloosahatchee Conditions Summary: Flow to the Caloosahatchee Estuary had a 7-day average of 4,523 cfs at S-79 with a 7-day average of 43 cfs coming from the lake at S-77. The 14-day moving average flow at S-79 is 4,759 cfs and has been in the damaging flow envelope (> 2600 cfs; RECOVER 2020) for 12 days.

S-77 (from Lake Okeechobee) and S-79 (to Tidal Basin) flow data along the C-43 and Caloosahatchee River. C-43 Basin Flow was calculated as the difference from S-77 and S-79.
